Perimortem C-Section

• To optimize maternal

cardiopulmonary resuscitation

• Rescue of a viable fetus >24 weeks

gestation is an important

consideration, but such rescue is

always secondary to the safety and

life of the mother

195

Contraindications

Perimortem C-Section

• Mother with serious brain injury but

otherwise hemodynamically stable,

fetus shows no signs of distress.

• Inability to adequately resuscitate

infant after delivery

• Extreme fetal prematurity/immaturity

196

Procedure

Perimortem C-Section

• Make a vertical midline skin incision

with a #10 scalpel blade beginning 2

to 3 cm above pubic symphysis and

extending to 1 cm below umbilicus

• Ignore any subcutaneous bleeding

unless it is arterial

– Clamp \ bleeding artery or use electro-

cautery unit to coagulate if available

Procedure

Perimortem C-Section

• Extend incision through

subcutaneous fat to rectus sheath.

• Grasp and elevate rectus sheath

using a toothed forceps

• Make an incision in the rectus sheath

with a Mayo scissors. Extend the

rectus sheath incision superiorly and

inferiorly with a Mayo scissors 199

Procedure

Perimortem C-Section

• Expose the uterus – the underlying

peritoneum should be visible

• Insert retractors to fully expose the

peritoneal membrane

• Grasp and elevate the peritoneal

membrane with a toothed forceps

• Incise the peritoneal membrane with

a Mayo or Metzenbaum scissors 201

Procedure

Perimortem C-Section

• Make reasonable attempts to protect

the bowel and bladder from injury

• Elevate the bowel off the field and

cover it with a saline soaked towel

• Place a bladder retractor over the

pubic symphysis to retract the rectus

sheath and bladder

202

Procedure

Perimortem C-Section

• Identify the position of the fetal head

by palpating the uterus

• Make a 2 to 4 cm midline vertical

incision in the uterus

– The amniotic sac will bulge through the

incision if the membranes are intact

• Place a finger into the uterine incision

and aimed vertically 204

Procedure

Perimortem C-Section

• Insert one blade of a bandage

scissors between the finger and the

uterine wall

– The other blade of the scissors should

be outside the uterus

• Extend the vertical uterine incision

fundally, superior and away from the

bladder

205

Procedure

Perimortem C-Section

• Rupture the amniotic membranes with

a clamp or other blunt instrument

• Carefully transect the placenta if it is

anterior to the fetus

• Insert a hand between the pubic

symphysis and the fetal occiput

208

Procedure

Perimortem C-Section

• Advance the hand to the base of the

occiput

• Flex the fetal head and apply gentle

anteriorly and superiorly directed

traction to elevate and deliver the

head

210

Procedure

Perimortem C-Section

• Deliver the entire fetal head

212

Procedure

Perimortem C-Section

• Suction the mouth and nose with a

bulb syringe

214

Procedure

Perimortem C-Section

• Deliver the shoulders in a manner

similar to that of a vaginal delivery

• Apply gentle upward traction on the

head while an assistant applies

pressure on the uterine fundus

– First deliver the anterior shoulder

– Deliver the other shoulder followed by

the torso and lower extremities

216

Procedure

Perimortem C-Section

• Clamp umbilical cord with hemostat

or umbilical cord clamp approximately

10 to 15 cm from fetus

• Attach second hemostat or clamp 2 to

3 cm distal to the first

• Cut umbilical cord between the

clamps with a Mayo scissors

• Resuscitate the neonate 218

Complications

Perimortem C-Section

• Maternal sepsis

• Maternal visceral injury

• Maternal hemorrhage

• Fetal injury secondary to delivery

• Possible benefits of maternal and / or

fetal survival should far outweigh

these considerations
